PURPOSE:To efficiently use a storage area and to simplify the rectangular area description processing by dividing a rectangular area to prescribed rectangular areas and describing them in a pattern storage device in an arbitrary order. CONSTITUTION:A pattern is described by a pattern describing means 103 and is stored in a pattern storage device 102 and is displayed on a pattern display device 101. When an arbitrary rectangular area designated with a dot as the unit will be stored in the pattern storage device 102, this rectangular area is divided into three, namely, a rectangular area from one end to the first pattern boundary, a rectangular area from the last pattern boundary included in the rectangular area to the other end, and a rectangular area between these rectangular areas, and these areas are described in the pattern storage device 102 in an arbitrary order. |
